Below is an email exchange I had with Rhys Ulerich regarding my inability to reproduce the
test case for the gsl_multiinear_wfit module. Rhys concluded thhat the problem was due to the
use of a different random number generator. As noted at the end of his email he suggested that I
ask that the example be documented as having used GSL_RNG_TYPE=mt19937_1999 or that a
new test be published for the new default generator.

I have been unable to get the sample code that executes the
routine gsl_multilinear_wfit.c (which I literally cut and
pasted from the on-line HTML documentation) to give an answer
that is the same or even close to what is given in the
documentation.

A quick sweep through the available random number generators (try
setting an incorrect GSL_RNG_TYPE value before running ./generate to
get a list) shows that the example in the documentation was produced
using the 'mt19937_1999' generator and not the current default.

Try running 'GSL_RNG_TYPE=mt19937_1999 ./generate | ./fit 19' to see
if it reproduces what the manual documents. It did for me.

If it does, please file a bug on savannah asking that either the
example be documented with this GSL_RNG_TYPE=mt19937_1999 detail or
the results be updated for the new default generator.
